Abstract
Thermal properties of polymers having aromatic rings related to lignin were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The relationship between chemical structures and thermal properties of polymers was discussed from the viewpoint of molecular design. It was found that thermal properties such as crystallization, relaxation in the glassy state and thermal decomposition temperature could be controlled by the appropriate arrangements of chemical bonds and functional groups such as phenylene group, methoxyl group, alkylene group and etc.
